If the Child’s Score is 35, the predicted value for Adult’s IQ is 110 (Option C).
How to calculate the predicted value?
The predicted value for the Adult’s IQ is calculated by using the graph given as shown below.
From the given graph, when the Child’s Score is 30, the adult's IQ value is approximately 100.
Also, from the given graph, when the Child’s Score is 40, the adult's IQ value is approximately 115.
So it is imperative to conclude that when the Child’s Score is 35, the adult's IQ value will be between 100 and 115.
Thus, the only value in the options that is between 100 and 115 is 110. So the adult's IQ value is 110.
